Why SKJ Builders

Professional Equipment. Engineering Standards. Owner on Every Job.

Most contractors show up with hand tools and guesswork. SKJ Builders arrives with the same equipment used on commercial sites.

CAT & Bobcat Equipment

CAT 305E2 mini-excavator and Bobcat T595 skid steer on every site — not rented weekend equipment or hand tools.

Laser-Level Precision

Every concrete pour laser-leveled to commercial tolerances — critical for epoxy coatings, pole barn floors, and workshop slabs.

4,000 PSI Minimum — Always

Air-entrained 4,000 PSI with compacted gravel base. Never the cheaper 3,000 PSI mix — because NY freeze-thaw cycles don’t forgive shortcuts.

Drainage Engineering

4” Schedule 40 perforated pipe, 3/4” washed stone, correct hydraulic gradient — systems engineered for decades of performance.

What Homeowners Say

Trusted by Binghamton Homeowners

★★★★★ 5.0 — Rated by local homeowners
★★★★★

“Rob poured our 30×40 garage floor and it came out absolutely perfect. Laser-leveled, no cracks after two winters. He was on-site the whole time, answered every question I had. Best contractor experience I’ve had in 20 years of homeownership.”

Vestal, NY — Garage Floor
★★★★★

“We had serious water in our basement every spring. Rob came out, assessed the whole yard, and installed a French drain system that solved it completely. First spring after — completely dry. The man knows drainage better than anyone I’ve talked to.”

S
Sarah M.
Johnson City, NY — French Drain
★★★★★

“SKJ Builders built our Trex deck and did the excavation for our addition. Two separate projects, both came out exactly as promised, on time, on budget. Rob is the only contractor we’ll call for anything heavy going forward. Honest, skilled, professional.”

Common Questions

Frequently Asked Questions

Answers to the questions Binghamton homeowners ask before hiring a contractor.

How much does a concrete garage floor cost in Binghamton, NY?

A typical 24×24 (576 sq ft) garage floor in Binghamton ranges from $3,500–$6,500 depending on base preparation, reinforcement, and finish. SKJ Builders pours 4,000 PSI air-entrained concrete with a properly compacted gravel base — specs that eliminate cracking and freeze-thaw damage. Call 607-760-1323 for a free site visit and exact quote.

Do you use subcontractors?

No. Rob Munson personally operates the equipment and manages every SKJ Builders project from start to finish. There are no subcontractors, no bait-and-switch crews, and no hand-offs. When you call, you speak directly to the person who will be on your property running the work.

How long does a French drain installation take?

Most residential French drain systems in Binghamton are completed in 1–3 days depending on length, depth, and site conditions. SKJ Builders uses CAT mini-excavators for precision trenching — faster and more accurate than hand digging. Proper installation includes 4” Schedule 40 perforated pipe, 3/4” clean washed stone, and correct hydraulic gradient to a legal discharge point.

Are you licensed and insured in New York?

Yes. SKJ Builders is fully licensed and carries general liability insurance in New York State on every project. Documentation is available upon request before work begins. We serve Broome, Tioga, and Susquehanna counties including Binghamton, Vestal, Endicott, Johnson City, Owego, Conklin, Kirkwood, and Windsor, NY.

Is composite decking worth the cost vs. pressure-treated wood?

Yes, for most Binghamton homeowners. Composite decking (Trex Transcend, TimberTech AZEK) lasts 25–50 years versus 10–15 for pressure-treated wood in NY weather. It requires no staining, sealing, or annual maintenance and carries a manufacturer warranty. The higher upfront cost typically pays for itself within 7–10 years in avoided maintenance and early replacement. SKJ Builders is a certified installer for both Trex and TimberTech.
